Remote code execution via undisclosed SMB flaw
Published Aug 9, 2022 · Updated Jan 2, 2025
Remote code execution in SMB on Microsoft Windows 11 version 21H2 before 10.0.22000.856 allows remote attackers to execute code. Microsoft has not published the affected SMB code path or the incorrect operation performed on untrusted network input. Exploitation requires user interaction and allows code execution that can read or alter data and interrupt the affected system.
